MAX1954A Datasheet Current-mode Pwm Buck Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1954A 19-3154; Rev 1; 5/05 EVAALVUAAILTAIOBNLEKIT Low-Cost, Current-Mode PWM Buck Controller with Foldback Current Limit.

General Description

The MAX1954A synchronous current-mode, pulsewidth modulation (PWM) buck controller is pin patible with the popular MAX1954 and is suitable for applications where cost and size are critical.

The MAX1954A operates from an input voltage range of 3.0V to 13.2V, independent of the IC supply.

The output voltage is adjustable down to 0.8V.

Key Features

  • foldback current limiting that greatly reduces input current and component power dissipation during output overload or short-circuit conditions. The compensation and shutdown control (COMP) input, in addition to providing compensation to the error amplifier, can be pulled low to shut down the converter. An input undervoltage lockout is provided to ensure proper operation during power sags to prevent the external power MOSFETs from overheating. Internal digital soft-start is included to reduce in.
